Located in the Central Fraser Valley, the Pacific Institution and Regional Treatment Centre is a multi-level security complex that houses a psychiatric care unit, a health centre, and a rehabilitation unit.
When the centre needed a new door control system to replace their fire alarm-based system, Correctional Service Canada selected Houle’s security team to provide the customized control system. The project included the replacement of five separate door control systems in five separate buildings (ranging from medium-to-high security), each with different needs. The new system is based around a redundancy-enabled PLC system with HMI control software to provide the custom user-interface.
All existing cabling had to be reused to reduce overall down-time and to maintain a fully operational and secure environment at all times. Houle relabeled all existing cables and re-terminated the door locks onto new high-current power supplies. The new system also re-used the existing end-of-line supervision resistors to provide cable fault supervision on the new platform.
Houle supplied technical and engineering help to assist with the design of the DDC Controls. Houle designed a system that utilizes seawater from the Burrard Inlet for free cooling and heat recovery. There was also a need to communicate via BACnet communications to equipment such as variable frequency drives, heat pumps, and electrical and energy meters. The design of the building had to be to LEED Gold standards; this included rainwater harvesting and grey water systems.
Working in an operational prison was a challenge. Along with having reduced access to locations because the prison was operational, Houle had to ensure all systems were functional at all times so that security was never compromised. With compressed time frames for installation, Houle installed new fibre optic cabling to meet higher security demands of the HMI touch-screen control stations. The system needed to be integrated with existing door hardware. Custom interface required various reviews and revisions to meet customer requirements.
Houle provided extensive documentation for this project, including as-built drawings/manuals, and operator manuals.
